Abstract

The utility model discloses a balance hole anti-overflow goes out carburetor, including the carburetor body, be equipped with float chamber and balance hole on the carburetor body, float chamber inner chamber communicates with each other with the external world through balance hole, and the balance hole is equipped with the vertical section, is connected with the turn groove at the lower extreme of this vertical section, still includes the cock body, and the cock body is barrel-shaped, and the vertical section is arranged in to the open end of cock body, and the turn groove is arranged in to the blind end of cock body, is equipped with rather than the communicating clearing hole of cavity on the perisporium of cock body, and this clearing hole is close to the blind end of cock body. Therefore, in the vibration process of the carburetor, fuel can be separated through the plug body when overflowing, so that the phenomenon that the fuel overflows the balance hole in fuel oscillation is avoided, meanwhile, the smoothness of the balance hole is ensured through the through hole in the plug body and the hollow space in the plug body, the atmospheric pressure is kept in the float chamber, and potential safety hazards caused by the overflow of the fuel can be eliminated.

Description

Balance hole anti-overflow carburetor

Technical Field

The utility model relates to a carburetor, concretely relates to balance hole anti-overflow goes out carburetor.

Background

The structure of carburetor includes float chamber, float, and the float is indoor to be full of the fuel, can produce the vibration after the engine starts, and the float chamber makes the inner wall reach atmospheric pressure through the balancing hole, and great vibration can make the fuel produce to vibrate very easily and spill over from the balancing hole, and the fuel that spills over can have the risk of burning, brings the potential safety hazard.

Disclosure of Invention

In order to solve the problem, an object of the utility model is to provide a balance hole anti-overflow goes out carburetor avoids the fuel to spill over when guaranteeing that the balance hole is unblocked, eliminates the potential safety hazard.

In order to achieve the above purpose, the utility model provides a following technical scheme: a balance hole anti-overflow carburetor comprises a carburetor body, wherein a float chamber and a balance hole are arranged on the carburetor body, the inner cavity of the float chamber is communicated with the outside through the balance hole, a vertical section is arranged on the balance hole, a turning groove is connected to the lower end of the vertical section, the carburetor also comprises a plug body, the plug body is barrel-shaped, the open end of the plug body is arranged in the vertical section, the closed end of the plug body is arranged in the turning groove, a through hole communicated with the hollow of the plug body is arranged on the peripheral wall of the plug body, and the through hole is close to the closed end of the plug body.

And an annular limiting ring is arranged on the inner wall of the vertical section, and the inner diameter of the limiting ring is smaller than the outer diameter of the plug body.

The outer wall of the opening end of the plug body is chamfered to form an inclined limiting wall.

The height of the turning groove is smaller than that of the plug body.

The utility model discloses a structure for send the carburetor vibration in-process, the accessible cock body carries out the separation when the fuel spills over, has avoided spilling over the balancing hole in the fuel shock, and the clearing hole on the cock body and its cavity guarantee the unblocked of balancing hole simultaneously, make the indoor atmospheric pressure that keeps of float, alright eliminate the fuel like this and spill over the potential safety hazard of bringing.

The invention is further described with reference to the accompanying drawings and the detailed description.

FIG. 2 is an enlarged view of A in FIG. 1;

fig. 3 is a perspective view of the plug body according to the embodiment of the present invention.

Detailed Description

The present invention will be specifically described below by way of examples.

As shown in fig. 1-3, the embodiment discloses an anti-overflow carburetor with a balance hole 3, which comprises a carburetor body 1, wherein a float chamber 2 and a balance hole 3 are arranged on the carburetor body 1, the inner cavity of the float chamber 2 is communicated with the outside through the balance hole 3, the balance hole 3 is provided with a vertical section 31, the lower end of the vertical section 31 is connected with a turning groove 32, the anti-overflow carburetor further comprises a plug body 4, the plug body 4 is barrel-shaped, the open end of the plug body 4 is arranged in the vertical section 31, the closed end of the plug body 4 is arranged in the turning groove 32, a through hole 41 communicated with the hollow of the peripheral wall of the plug body 4 is arranged on the peripheral wall of the plug body 4, and the through hole 41 is close.

An annular limiting ring 310 is arranged on the inner wall of the vertical section 31, and the inner diameter of the limiting ring 310 is smaller than the outer diameter of the plug body 4. This construction prevents the plug 4 from entering the vertical section 31 with the fuel and from blocking the passage holes 41, so that the balancing holes 3 remain always open.

The outer wall of the opening end of the plug body 4 is chamfered to form an inclined limiting wall 42. The limiting wall 42 can be abutted against the port of the limiting ring 310, so that the flexible range of the plug body 4 can be improved, and the plug body 4 has better buffering performance when fuel overflows.

The height of the turnaround slot 32 is less than the height of the plug body 4. This arrangement prevents the plug body 4 from tipping over in the turnaround slot 32 and rendering the plug body 4 inoperative.

By adopting the technical scheme, in the vibration process of the carburetor, fuel can be blocked by the plug body 4 when overflowing, so that the balance hole 3 is prevented from overflowing in fuel oscillation, meanwhile, the smoothness of the balance hole 3 is ensured by the through hole 41 on the plug body 4 and the hollow space thereof, the atmospheric pressure is kept in the float chamber 2, and thus the potential safety hazard caused by fuel overflow can be eliminated.
